Lumin U2 or Aurender N200


Looking for thoughts on these two streamers: Lumin U2 and Aurender N200.

I’m fully aware of the limitations and features from UI and Roon integration to design concepts and implementation (power supplies, caching, display, etc.)


Hoping to hear from those who had compared these two streamers. I’m also absolutely not interested in hearing from “it’s all 1s and 0s” crowd - this isn’t that forum and I kindly ask you to please stay out of this discussion.

Thanks and Happy Holidays to you all!!!

My fibre and Cisco switch is only 3 weeks old in my system, and I only have 1 set of modules to try :) I know my system right now with fibre into the LPS powered etherREGEN then ethernet into the DAC sounds pretty darn good, many levels better than ethernet direct into the DAC, but I'll remove just the fibre and do cat 6 into the ER and compare. 

Just went back and forth between fibre and cat 7- (its actually a cat 7 cable) both from the Cisco switch into the etherREGEN powered by Plixir BDC. Used Keb Mo - "I was wrong".

Really difficult to hear any difference- I had to go back and forth a dozen times:

Bass pretty much equal, if anything there is a little more bloom with fibre- I don’t find any difference with body- but treble- in this case cymbals/harmonica is a touch more prominent and forward with fibre. Gives the impression it is a little more detailed, more air, but I could see that interpreted as glare.

Doesn’t come across as hardness or glassi-ness though. I’m pretty confident I don’t think I could tell the difference if someone tested me- and this was just one track- more listening required!

edit: if someone was curious optical/transceivers are from AS

@mclinnguy that’s a great test track and a very good recording.
Out of curiosity, what Cat7 cable are you using? That’s between the etherregen and streamer correct?

Between ER and Weiss is an Audio Sensibility Supra cat 8- they modify it by cryo'ing the cable and adding Telegartners- very reasonable price 

AS Supra ethernet

That ethernet cable remained in place. I only swapped the cat 7 from the Cisco switch to the ER- it is 50' $22 one from Monoprice and goes up inside the back wall across the ceiling and down the wall in front of the gear. 

Yes, before you suggest I am now researching Muon stuff :) Pricey for sure!

Actually I recall you having an Eno before also; it didn't work for you? 

I prefer to avoid more wall warts, and more conversions. I find the possibility of introducing more AC line noise via additional active devices far outweighs any idea that the 30’ feet of Ethernet from my outside wall is going to help.

I do however use this right before my streamer’s switch both for noise and to add 4kV of isolation and surge protection:
